James Cameron is not only an amazingly talented filmmaker, he's also crazy.
He is planning to dive to the bottom of the Mariana trench, the deepest point in the whole ocean.
And no, he's not funding some adrenaline-junkie scientists, he's going himself.
He wants to find out what's at the bottom of the 36,000ft deep trench. That's over 6.8 miles down!!
The pressure there is over 8 tons per square inch.
That's why he's crazy. Best of luck, Mr. Cameron.
